Chunky M&M Cookies (Gramma’s Amish recipe collection)
Ingredients
- 6 tablespoons butter softened
- 1 cup brown sugar
- 1 cup granulated sugar
- 3 large eggs
- 1 1/2 cups peanut butter
- 2 teaspoons baking soda
- 4 1/2 cups old fashioned rolled oats *see note
- 4 oz. chocolate bar of your choice, finely chopped.
- 1 cup M&Ms
Instructions
Preheat oven to 325 degrees.
- In a medium sized bowl, cream butter and sugars together. Add eggs and peanut butter, then mix well until the mixture is fluffy and well incorporated. Add baking soda and rolled oats and mix to combine, then fold in the M&Ms and chocolate chunks.
- Drop the cookie dough by tablespoonfuls (or with an ice cream scoop) onto a greased cookie sheet *see note. These cookies tend to spread out a good bit in the oven so be sure to keep them several inches apart.
- Bake the cookies in the preheated oven for 12-15 minutes until the bottoms and edges are starting to brown. Allow the cookies to rest for 5-10 minutes, then remove them from the baking sheets and enjoy!

This Recipe is another treasure I found in grandma’s recipe box. Perhaps I should call them treasure chest cookies?! These cookies are also known as Monster cookies and if you wish to make them festive for Christmas or Valentine’s day you can add Christmas or Valentine’s day M&Ms. If you are wanting to make cookies for memorial day or fourth of July, you can even use red white and blue M&Ms!
Feel free to pin for later and let me know how they turned out for you in the comments below!
